Abstract: PURPOSE: To return a tone arm to a stop state and eliminate the malfunction of the arm by rotating a control cam which leads in and down the tone arm forward at the start and reversing the rotation by a changeover means when rejection operation is done on the way.  
     CONSTITUTION: As a drive motor runs, a control cam 6 rotates and its forward rotation causes the cam 6 to rotate forward a leading-in lever 9 by way of a leading limiter 8, thus pushing the pin 11 of a brake drum 1 fixed to the revolving shaft 7 of a tone arm to lead-in the arm. As the motor runs backward, a returning limiter 17 pushes the pin 11 to return the arm in the rest position. When a power source +B is turned ON and a start SW 26 is turned ON in the static position, an FF 21 is set and one of its outputs operates a forward driving circuit 22, thus running the motor 3 forward. The forward rotation of the cam 6 detaches its protrusion 18 from the SW 1, then moving terminal 25 touches the terminal 25a, thus turning OFF Tr 24. When a reject switch 27 is turned ON, the FF 21 is reset and a backward driving circuit 23 is operated by the other terminal output, by which the motor is run backward.

Abstract: PURPOSE: To enable to make a substantial reduction in the power consumption of the integrated circuit by a method wherein, in the case of the circuit that is operated by high voltage, an I 2 L circuit and other low voltage operation circuit are inserted in the part whereon a constant current is running.  
     CONSTITUTION: An almost constant current runs on the emitters of transistors Q21 and Q22, and the I 2 L circuit is inserted between the emitter of the transistors Q21 and Q22 and the emitter. The injector terminal of the I 2 L circuit is connected to the emitter on the transistors Q21 and Q22, and a Gnd terminal is connected to the Gnd terminal of an ordinary circuit. As a P-N junction is formed between the injector terminal of the I 2 L circuit and the Gnd terminal, forward voltage component (about 0.7V or thereabouts) of voltage diodes located at both ends is generated. Since the source voltage of the ordinary constant- current circuit can be set sufficiently larger than that of the forward voltage of the diode, the I 2 L circuit can be inserted without causing any trouble.
